Display substrate, manufacturing method and display device

The invention provides a display substrate, a manufacturing method and a display device. The display substrate comprises a driving circuit arranged on a substrate, and the driving circuit comprises a first node control circuit; the first node control circuit comprises a first transistor and a second transistor; the grid of the first transistor is electrically connected with the first control end, the first pole of the first transistor is electrically connected with the first voltage end, and the second pole of the first transistor is electrically connected with the first node; the grid of the second transistor is electrically connected with the second control end, the first pole of the second transistor is electrically connected with the first node, and the second pole of the second transistor is electrically connected with the second voltage end; the display substrate further comprises a first connecting structure arranged on the substrate body. The first transistor is connected with a part of the first connection structure; and/or the second transistor is connected with a part of the second connection structure. According to the invention, the conversion between the bidirectional scanning drive circuit and the unidirectional scanning drive circuit can be realized only by adding two masks.
